This insect trap is engineered for 3-way protection. First, a UV fluorescent bulb generates a warm light, attracting insects. Then a second lure, an exclusive Ti02 titanium dioxide-coated surface, produces CO2 (the same gas we emit when we exhale) that’s irresistible to mosquitoes. Third, a powerful, yet whisper-quiet vacuum fan sucks insects into the retaining cage where they dehydrate and die.
